C represents a transverse dovetailed tongue or spline,rwhich is arranged on the upper side of the bed-plate, at a suitable distance from the rear end thereof, and is firmly secured to the bed-plate,either by bolting itthereto or in any other suitable manner.

D represents a series of vertical standards, which have the widenedtreads or feet Eat their bases, are widened or swelled at a suitable distance fromtheir lower ends on opposite sides, to form transverse enlargements F, are similarly swelled on'opposite sides at a suitable distance above the enlargements F, to form transverse horizontal enlargements G, and have bearings H formed at their upper ends. The lower ends of the said standards are provided with transverse dovetailed recesses I, to receive the dovetailed tongue or spline C, and

a gib, K, is placed between the rear' side of 65 the said spline or tongue and the opposing sides of the recesses I, as shown. The said standards are arranged at suitable regular distances apart, and are each provided with a clampingscrew, L, which bears against the rear side of the gib and serves to secure the standards firmly in position.

M represents a shaft or rod,which extends transversely through the standards D at a suitable distance below the enlargements F. Said shaft or rod is fixed in the standard, and is not adapted to rotate, and serves the purpose of bracing the standards and preventing lateral vibration thereof. The ends of the said rod or shaft project beyond opposite sides of the machine, and on one end of the said shaft is fitted a loose driving-pulley, N, and on the opposite end thereof is fitted a loose double pulley, O. On the inner end or side of the loose driving-pulley N is a peripherallygrooved collar, P, and one member, R, of a clutch.

' S represents a miter gear-wheel, which is also loose on the shaft or rod M, and is provided on its outer side with a clutch member, T, which is adapted to be engaged by the clutch member R, so as to enable the rot-ary motion ofthe driving-pulley N to be communicated to the miter-wheel S.

On the upper side of each die-plate, on opposite sides ofthe same, are parallel flanges 4.o T' represents a series of formers, each of which is of the exact size and shape of the horseshoes to be made by the machine, and said formers are provided on their under sides with the depending coreU,the shape of which t5 corresponds with the inner side of the horseshoe, a recess or 1nold,V', bein g thereby Vformed in the edge of each former. From the front end of each former, at the upper side thereof, projects a lip or Harige, lV', and from the rear 5o end of each former proj eets an arm,X. Each former is arranged on the upper side of its companion die-plate, and the opposing sides of the arms X and O are llattened,so that said arms bear snugly against each other, and the said arms are inserted in countersunk openings Y', which are made transversely in the enlarged portions F of standards D, as shown in Fig. 4. rlhe inner sides of the foi-mers and die-plates enter recesses in the front sides of 6o the standards D, and thereby' the die-plates and formers are maintained in perfectly horizontal planes. The upper side of each dieplate is at a suitable distance below the under side of its companion former, and thereby a horizontal opening, 7i', is formed between each die-plate and its companion former, as shown in Fig. 4.

standards, which bear against the gibs, and.

thereby firmly secure the standards in place.

E represents a shaft, which is journaled in suitable bearings in the standards B". To one end of the said shaft is keyed a worm-wheel, F", and a suitable number of eccentrics, G2, are also secured to the said shaft and arranged at suitable regular distances apart.

H2 represents a dovetailed tongue or spline, which is arranged transversely on the upper side of the base-plate at a suitable distance from the front end thereof.

I represents a series of guide standards, which have dovetailed recesses in their lower ends to receive the said tongue or spline, and said standards are secured in position at suitable regular distances apart by means of gibs K2 and elampingscrews U, as shown in Figs. 2 and ft.

M" represents a series of longitudinal rods, which are guided in bearings in the upper ends of the standards l2 and are adapted to reciprocate therein. To the front end of each rod lll2 is pivotally connected a pitman, N1", and the said pitmen are provided at their front ends with eccentric-straps O2, which connect them to the eceentrics (l2. The rear end of each rod l\l is provided with a broadened head, I, and in each of the said heads are pivoted the front ends of a pair ol' arms, R". The said arms are adapted to move laterally in horizontal plane, and are provided each at its rear end with a vertical pin, S'.

On the upper side of each die plate N' is arranged a plate, T2, the said plates T being adapted to be guided in a longitudinal direction on the die-plates by the flanges of the latter. The upper side of each plate '1" is inclined longitudinally, as shown in Figs. 2 and 4, and each plate 'lz is provided at a suitable distance from its inner or rear end with a transverse slot, U2. The pins S2 of the arms R2 enter the said slots and are normally in the openings R' of the die-plates, so that the pairs of arms R are arranged side by side and in contact each with its fellow. Each former is provided with a number of vertical openings, c, which correspond with the nail-holes in a horseshoe, and each plate T2 is provided with similar openings, d, which are adapted to regis ter with the openings c when the plates are moved inward under the formers, as will be hereinafter described.

V2 represents a series of brackets, which project from the front sides ofthe standards D, and

have the rearwardly-extending arms, which are secured in openings in the enlarged por- IOC tions G of said standards by' means of setscrews W2, as shown in Fig. 4.

X2 represents a series of plunger-rods,which are guided in vertical openings in the brackets V2, and have'their upper ends provided with eccentric-straps Y2, which engage the eccentrics B. In the lower end of each plungerrod X2 is made a vertical. recess or socket.

Z2 represents a series of hammers or plungers, the constructionof each of which is as follows: Y

A3 represents a plate of suitable size, which is substantially in the form of a horseshoe and is provided at a suitable distance fromits front and rear end with transverse slots B2. From the upper side of the plates near the center of the same, projects a spindle or arm, C2, which is adapted to enter the recess or socket in thelower end of one of the plungerrods X2, and is secured therein by means of a set-screw, D3.

E2 represents a pair of plates, which are arranged on the lower side of the plate A2, and are secured thereto by means of bolts F2,which pass downward through the slots B3 and enter the said plates. The outer sides of the plates E2 conform to the contour of the plate A2, and in the opposing edges of the said plates E2 is made a tapered threaded opening, G2.

H3 represents a tapered screw-plug, which engages the said opening. By loosening the bolts F3 and turning the tapered screw-plug the plates E2 may be moved laterally toward or from each other, so as to adjust the ham' mer or plunger to any desired width, as will be readily understood. The plates Ea are provided with vertical openings, which are similar to the openings c and d of the formers and plates T2, respectively, and in the said openings in plates E are inserted the upper ends of vertical depending punches 12, which are adapted to punch the nail-holes in the horseshoes, as will be hereinafter described, and are secured to the plates F3 by means of setscrews K2.

L3 represents a feed-box, which is arranged transversely over the saws and over the outer ends of the die-plates and has its inner side open, as shown in Figs. 4, 8, and 9. In the upper side of the feed-box, at suitable regular distances apart, are vertical transverse t slots M2.

N2 represents a feedlbar, which is arranged in the feed-box, extends entirely throughout the length thereof, and has one end enlarged, as at O2. 0n the under side of the feed-bar is a longitudinal groove, P, and from the outer side ofthe feed-bar depends a vertical flange, R2.

S2 represents a series of stop-pins, which project from the upper side of the feed-bar N:E and work in the slots M2, the function of the said pins and of the slots being' to limit the lateral play of the feed-bar in the feed-box. From the innerside of the feed-bar, near the upper edge thereof, project a series of screw-eyes or keepers, T2, and in the rear side of the feedbar and at a suitable distance from its upper sido is a horizontal longitudinal open slot, U2. The projecting lips W of the formers enter said open slot U3, and therebysecure the feedbar on the formers and over the outer end of the die-plates and over the saws.

V2 represents rods, which project forward from the standards D, at suitable distances apart, and have eyes formed in their outer ends and arranged on the sides of the screw-eyes T2. A rod, W2, passes through the eyes in the rods G2 and through the screw-eyes T2, and thereby serves to connect the feed-bar to the rods V2, the function of the latter being to secure the feed-bar against-movement.

Xs represents arms or brackets, which project rearward from the end standards, D, near their upper ends. In the rear ends of the said arms or brackets is journaled a shaft, Y2, which is provided with wormwheels Z2, that engage the worm-wheels Z.

A2 represents a miter gear-wheel, which is secured to one end of the shaft Y2.

B4 represents a horizontal arm or bracket, which is secured on the outer side of one of the end standards D. In the said arm or bracket is jonrnaled a vertical shaft, C4, which is provided at its upper end with a miter-wheel, D4,

To the lower' .end of the said shaft is secured a miter-wheel,

that meshes with the wheel A4.

E4, lthat meshes with the wheel S.

From the foregoing description it will be understood that when the pulley N is rotated and is geared to the wheel S rotary motion is transmitted to the shaft C* by the wheel E, from the shaft C* to the shaft Y2 by the mitergears A4 and D, and from the shaft Y2 to the shafts Y by the worm-gears Z2 and Z,

F2 represents a pair of bearings which project from one side of the base-plate, and in the said bearings is journaled an incline-shaft, G4, which is provided at one end with aworm, H, that meshes with the worm-wheel F2, and is provided at its opposite end. with a miterwheel, I4, that meshes with the wheel S.

From the foregoing description it will be understood that the rotary motion of the Wheel F,when the driving-pulley N is clutched thereto, will be transmitted to the shaft Gr4 through the ruiter-wheel I2, and from the said shaft to the shaft E2 by the worm H4 and wormwheel F2. The pulley O is connected to a driving-pulley on a suit-able counter-shaft (not shown) by means of asuitable endless belt, K2, which is illustrated by dotted lines in Fig. l.

The operation of our invention is as follows: When the horseshoemachine is in its initial position, the vplates T2 are drawn outward from between the die plates and formers, the saw-arbor is lowered, the pluugers or h'ammers are raised, and the arms R2 are in contact with each other in pairs, and the pins S2 are in the openings R of the die-plates. A bloom is heated in asuitable furnace, is passed through the passes of a set of rolls of the usual construction in a suitable manner, the said rolls being adapted to convert the bloom into a rod or blank, e, which is of suitable length to make a number of horseshoes, according to the capacity of the machine, and the said rolls make the creases which are to appear in the horseshoes in the said blank-rod, as is now customarily done. The said blankrod,while still heated and ductile, is fed from the last pass of the rolls directly into the groove P3 of the feed-bar N3, said blank-rod being supported upon the bottom ledge or ilange of the feed-box L3, as shown in Fig. 9. The operator then grasps the feed-box and moves the same outward from the standards D, thereby causing said feed-box to move from the feedbar, so that the lower ilange or ledge of the feed-box. passes from under the blank-rod e, and thereby causes said blank-rod to drop upon the inner end of the plates T2 and to bear against the inner sides of the pins S2. The mechanism of the horseshoe-machine is so timed that as soon as the blank-rod is dropped upon the said plates T2 the eecentrics D and A pass their lower dead-centers and consequently draw the plunger-rods X2 and the liitnlan C' upward, thereby elevating the plungers and the punchers attached thereto, and also elevating the saw-arbor and the saws, so as to cause the upper edges of the latter to rise between the die-plates, and consequently cut the blank-rod into pieces of suitable length to be bent into horseshoes. The saws and the plungers or hammers then begin to descend, being caused to do so by the eccentrics A B', as will be readily understood, and the eccentrics G and pitmen N2 then cause the rods M2 to move forward, and consequently impart forward longitudinal movement to the hinged or pivoted arms R2, thereby causing the pins S2 of the latter to engage the rear sides of the horseshoe-blanks and move the latter and the plates T2 forward. As the said blanks and said plates inove forward, the central portions of the blanks first strike against the front ends of the depending cores U of the formers, which cores arrest the forward motion of the central portions of the blanks. The pins S2 impinge against the curved sides of the formers as the arms R2 continue to move rearward, thereby causing the said pins to be guided in the cam-slots, which are formed between the outer sides of the formers and the inner sides of the openings P of the die-plates, the result being that the said pins bend the still heated blanks around the cores of the formers, thereby causing the said blanks to :till the molds of the formers and to bear between the lower sides of said formers and t-he upper sides of the plates T2. Owing to the slots U2, with which said plates T2 are provided, the pins S2 are caused to recede from and approach each other as they travel around the curved sides of the formers, and said plates are caused to move inward under the formers and to keep pace with the said pins, so that the blanks are at all times maintained upon the said plates while being bent around the cores of the formers.

Owing to the inclination of the upper sides of the plates T", the molds in the formers are deeper at the points thereof corresponding to the heels of the shoes than they are at their outer sides, and the shapes of the molds are such that the heels of the blanks are contractd in width, thereby as the pins S2 travel around the sides of the formers, when they approach the rear ends thereof, the inner sides of the openings P of the die-plates cause the pins S2 to swage the ends of the blanks in the molds and thereby give the horseshoes the necessary swell-heels and complete the operation of forming the horseshoes, so that no subsequent forging or manipulation of the horseshoes will be necessary. By the time that the pins S2 reach the rear ends of the cam-slots between the dieplates and the formers, and before the rods M2 and arms R2 start in their reversed longitudinal movement, the plungers or hammers have been lowered by the plunger-rods and their operating eecentries or cams B', so that the punches have descended through the now aligned openings c dof the formers and plates T2 and are being forced downward through the horseshoe-blanks, so as to punch the necessary nail-holes therein.

While the plungers are at the lower end of their movement and the punches have transxed thehorseshoes,said plungers and punches serve to hold the horseshoes rigidly in place in the molds of the formers. As the arms R2 recede,the pins S2 are caused to pass backward around the sides of the formers and to impinge so iirmly against the sides of the horseshoe-blanks that the swells or enlargements made in the outer edges of the same by the act of forcing the punches through the horseshoes are rolled out, thereby restoring the outer edges of the horseshoe-blank to the requisite configuration and imparting finished surfaces thereto. lt will be understood that as the pins S2 recede they draw the plates T2 outward with them, and as the horseshoe-blanks are still held in the molds ot' the formers by the punches, as before stated, the said plates T2 move from under the said horseshoe-blanks so as to uncover the openings P in the die-plates. By the time that the plates T2 are withdrawn entirely from under the formers and the horseshoes a second blank-rod is fed into the feedrod, the saws rise and cut the same into lengths, as before described, and the plungers or hammers rise simultaneously with the saws, withdraw the punches from the completed horseshoes, and the latter then drop in a finished condition through the openings P of the die-plates and through the openings B of the base or bed plate onto the Hoor or into a suitable receptacle.
